Alexander Semenov is a marine biologist, specializing in invertebrates. He’s the head of the divers’ team at Moscow State University’s White Sea Biological Station where he organizes and manages all sorts of work, often diving in harsh conditions.
Semenov is also a professional photographer. With over 9 years of experience under his oxygen tank, he’s mostly interested in scientific macrophotography in natural environments. “This practice makes it possible to observe animals that cannot be properly studied under laboratory conditions, such as soft-bodied planktonic organisms or stationary life forms living on the seafloor,” the diver explained on his flickr profile. “My personal goal is to study underwater life through camera lenses and to boost people’s interest in marine biology. I do this by sharing all my findings through social media and in real life, through public lectures, movies, exhibitions, and various media events.”
The video clip you’ll find below is perfect proof that Semenov loves what he does as much as the sea itself. During one of his dives under the ice in the White Sea in Russia, Semenov recorded a creature known as the sea angel. The high-quality footage reveals the tiny sea slug’s beauty as well as Semenov’s incredible skill controlling the camera.
